Abstract

Zur Herstellung von kreisrunden Ausnehmungen, insbesondere wahlweise auch Passungen oder Gewindebohrungen, mit stufenlos veränderlichem Durchmesser im vollen Material, mittels eines durch eine geeignete Maschine, beispielsweise eine CNC-gesteuerte Bohr-oder Fräsmaschine sowohl um seine eigene Achse als auch um die Ausnehmungsachse rotierend angetriebenen, fräsend arbeitenden Werkzeuges, bestehend aus einem mit Stirnschneiden zum Erzeugen einer Kernlochbohrung versehenen Fräser und einer Einspanneinrichtung für diesen, wird eine Kombination von Einspanneinrichtung und Fräserausgestaltung vorgeschlagen bei der teils zur Verringerung des axialen Schneidwiderstandes und teils zur Einstellung eines absoluten Rundlaufes des Fräsers in Verbindung mit einem eine Anzahl dreickförmiger eine V-förmige Schneidgeomtrie bildenden Stirnschneiden aufweisenden Fräser eine Einspannvorrichtung umfasst, die eine wenigstens zwei voneinander unabhängig verstellbare und zu den Schneiden des Fräsers in axialer Richtung gleichliegend am Fräserschaft angreifende Spannbacken aufweisende Spannzange sowie eine im axialen Abstand zu den Anlagepunkten der Spannbacken am Fräserschaft angeordnete als konische Ringfläche ausgebildete Zentrierfläche für den Fräserschaft besitzt. For the production of circular recesses, in particular optionally also fits or tapped holes, with stepless variable diameter in the full material, by means of a by a suitable machine, for example a CNC-controlled one Drilling or milling machine both on its own axis as well driven milling around the axis of the recess Tool, consisting of one with forehead cutting Generate a core hole and a milling cutter Clamping device for this will be a combination of Clamping device and milling cutter proposed at which partly to reduce the axial cutting resistance and partly for setting an absolute concentricity of the milling cutter in conjunction with a number of triangular a V-shaped Milling cutter forming end cutting edges a jig comprising one at least two independently adjustable and to the cutting of the Milling cutter in the axial direction on the milling cutter shaft attacking chuck jaws and a axial distance to the contact points of the clamping jaws on the milling shank arranged centering surface designed as a conical ring surface for the milling cutter.
